How to connect HubSpot to Mailchimp
- Connect your HubSpot portal. Authorize Autonoly to access your HubSpot portal via OAuth 2.0. Select the specific HubSpot hubs — Marketing, Sales, Service, CMS, Operations — you want Autonoly to interact with.
- Configure scope access and data mapping. Define which HubSpot objects (contacts, companies, deals, tickets) Autonoly can read and write. Map HubSpot properties to fields in your other connected platforms for accurate data sync.
- Connect your Mailchimp account. Authorize Autonoly to access your Mailchimp account via API key or OAuth. Autonoly will automatically discover your audience lists, tags, and existing automations.
- Configure audience access and data mapping. Select which Mailchimp audiences Autonoly can read and write. Map subscriber fields from external platforms to Mailchimp merge tags for accurate personalization.
- Pick your trigger and action. Choose the HubSpot event that should start the workflow, then the Mailchimp action it should run. Add a condition step if only some records should pass through.
- Test with one record, then turn it on. Run the workflow once against a real record and check the result in Mailchimp before enabling it.
What to watch when syncing HubSpot into Mailchimp
Decide the direction of truth
When both systems can change the same field, name one as authoritative or you will get a loop where each overwrites the other.
Filter at the trigger
Keep drafts and test records out by adding a condition immediately after the trigger rather than cleaning up downstream.
Handle the failures
Decide what happens when the destination rejects a record: retry, skip and log, or stop the workflow. Silent failure is the worst option.
Start with one record
Run the workflow once against real data and check the result before enabling it on everything.
Frequently asked questions
How do I connect HubSpot to Mailchimp?
Connect both accounts to Autonoly, choose a HubSpot trigger such as “Contact created or updated”, then pick the Mailchimp action you want to run. The workflow goes live as soon as you save it — there is no code to write and nothing to host.
Is the HubSpot to Mailchimp integration free?
Autonoly has a free plan you can build and run this workflow on. Paid plans add volume and advanced steps. See the pricing page for current limits.
How quickly does data sync between HubSpot and Mailchimp?
Workflows run as soon as the HubSpot trigger fires. You can also run them on a schedule if you would rather batch updates than send them one at a time.
Can I filter which HubSpot records reach Mailchimp?
Yes. Add a condition step between the trigger and the action, and only records matching your rule continue. This is the usual way to keep test or draft records out of a production system.
Do I need a developer to set this up?
No. The builder is visual, and both HubSpot and Mailchimp connect through standard authentication. If you do want code, you can drop into a script step at any point in the workflow.
